First of all, I think we all agree that with some of the early Ada 83 compilers, compiling an specification would force a recompilation of all dependent units, even if the specification had not changed since it was last compiled. Certainly the Alsys ActivAda compilers worked that way. IIRC DEC Ada generally did not unnecessary recompilations. Clearly unneeded compile time, or any other form of wasted time, is not desirable. But the leading Ada 95 compilers, GNAT and ObjectAda, do not exhibit this behaviour. We're fighting yesterday's battles here.
